It took a bit, but I found an okay-ish picture of the army on the display board I made for it.
You can see Scarlet Witch behind Hulk. The flying potato on the right was replaced with another Valkyrie for competitions, I just proxied it for training battles. The assassin in front of Hulk is Black Widow, played by Sly Marbo, proxied with the assassin model.
Oh, and I had misremembered. I didn't have Thor, because I had 3D-printed a HUGE thunderhammer for him, but hadn't gotten another Vertus Praetor model and was planning on using Ogryn arms, etc etc. Anyway, left to right, the Custodes were: Winter Soldier (Shield Captain with spear), Captain America (Trajan), Iron Man (Shield Captain on Dawn Eagle), Vision (Shield Captain on Dawn Eagle), and Hawkeye (standard bearer with the 5+ invul and the Gatekeeper relic - I wasn't going for combat optimized, just wanted to do the best I could with a thematic army).
It was fun to model and set up. Not fun to play at a tournament - got crushed pretty easily.
